The ITR wrist strap expands the possibilities and routines of the micro and super micro ITR. Included in this kit should be two velcro clips that will clip on to the micro or super micro. Advantages are you can perform routines such as Fearsons Floating Cigarette with the ITR making it self resetting and easily repeatable in a walk around situation. Works perfect for the floating finger routine! When you raise youir hand the ring flies away, when you lower your hand the ring floats smoothly down to the hadn that's wearing the ITR (can even float on to your finger with some practice.) You can easily lock the line since the thread feeds right across your hand, giving you more control over the levitating object.
